# Documentation

type Location = String #

A location is a relative path within the static subsite at which resource(s) are made available. The location can include slashes to simulate directories but must not start or end with a slash.

type Generator = Q [Entry] #

An embedded generator is executed at compile time to produce the entries to embed.

## Entry

data Entry #

A single resource embedded into the executable at compile time.

This data type is a settings type. For more information, see http://www.yesodweb.com/book/settings-types.

Instances

Default Entry # | When using `def`, you must fill in at least `ebLocation`.
Methods def :: Entry #

ebHaskellName :: Entry -> Maybe Name #

An optional haskell name. If the name is present, a variable of type `Route `EmbeddedStatic`` with the given name will be created which points to this resource.

ebLocation :: Entry -> Location #

The location to serve the resource from.

ebMimeType :: Entry -> MimeType #

The mime type of the resource.

ebProductionContent :: Entry -> IO ByteString #

If the development argument to `mkEmbeddedStatic` is False, then at compile time this action will be executed to load the content. During development, this action will not be executed.

ebDevelReload :: Entry -> ExpQ #

This must be a template haskell expression of type `IO `ByteString``. If the development argument to `mkEmbeddedStatic` is True, this action is executed on every request to compute the content. Most of the time, `ebProductionContent` and `ebDevelReload` should be the same action but occasionally you might want additional processing inside the `ebProductionContent` function like javascript/css minification to only happen when building for production.

ebDevelExtraFiles :: Entry -> Maybe ExpQ #

Occasionally, during development an entry needs extra files/resources available that are not present during production (for example, image files that are embedded into the CSS at production but left unembedded during development). If present, `ebDevelExtraFiles` must be a template haskell expression of type `[`Text`] -> IO (Maybe (`MimeType`, `ByteString`))`. That is, a function taking as input the list of path pieces and optionally returning a mime type and content.
